Glen,

After the shop installs the motor & transmission, will they then complete wiring & plumbing and get the car running?

That's the plan, Tim. They will be doing the exhaust as well. I've supplied the headers; they will do the cats, the mufflers and the rest of the exhaust.

Cheers!
Glen

I hope they commit to doing something in good time!

[xb-60]

BJ, all I can say is that they are committed to having it finished as quickly as possible, given COVID (as in resource complications) limitations. As in most workshops, cars there are taking up space, and will be out the door as soon as is practical
I've known these guys for decades, and I trust them.

Cheers!
Glen

Greetings all,
Still slow going because of specialist labour shortages, but engine 'refresh' should be completed early this week, so engine and Toploader should meet up soon.
Been discussing (again) re- which flywheel to use. My mech. is still trying to impress on me the advantages of a lightweight flywheel, but I want to stay with a standard mass flywheel.
My overall gearing in first gear is quite high, hence my preference for standard mass.

Cheers!
Glen

Sheesh, that was posted back in July!
Engine has been complete and ready for some time now, but information for the correct flywheel/clutch/HTOB for a 302W mating with a Toploader are - for some unexplainable reason - hard to track down (here in Australia), would you believe?

Cheers!

Impossible to believe. Damn, we could have thrown a TL and 302W together on a Saturday afternoon back in high school.

I never would have thought that. I know Cleveland's were popular down your way, so I just thought Windsor's would also be? Cheers, Dennis

Good Morning Glen. I would still consider a lightened flywheel (Stock 28lbs, lightened 22lbs) I had one in the V-8 RX-7, never saw a disadvantage, just a quicker revving 302, no slipping of the clutch to get moving (Wide ratio Tremec World Class T-5) Of course that's just my $.03 Buddy. Cheers Tom.

Tom is right. My aluminum flywheel is less than 20 lbs. and I love it. Yes, I know I have a big FE with a 3.54 rear, but it really is not a whole lot different taking off from a stop than driving any other car with a clutch. It might even bit a little safer because it revs down faster not having the stored energy.

Glen,

You may not have many options for the flywheel and clutch combo. I had to replace the flywheel, clutch and pressure plate on the race car and there are very few manufactures that make one for the Toploader input shaft. Most of them are setup for Tremec transmissions.

McLeod still offers a combo for the Toploader. I used quartermaster last time and they no longer offer an option for a Toploader.

All input on flywheel mass appreciated

There's a "however" though....so here's my thinking:

My differential ratio is 2.92, and my Toploader's highest ratio (4th gear) is of course 1:1
A popular/typical choice for many has been a Tremc TKO gearbox with a diff. ratio of 3.54

Comparing these two setups shows my WR TL overall first gear ratio at 8.12:1 whereas with that TKO and 3.54 combination, the overall first gear ratio is 10.16 - so, significantly higher for mine.
Further (but not flywheel mass related), comparing top gear ratios for both combinations results in 2.92 (WR TL) and 2.90 (TKO600)

My point is that for easier starts, for me, a standard mass flywheel is a better option. Also, I have learned/experienced advice that a standard mass flywheel is the way to go.
So ....at this point, and having weighed up the valued advice from my learned friends here, a standard mass flywheel it is

Cheers!
Glen

[Alfa02]

Oh, alright Glen, just because you own the Cobra, I guess you can install a stock one Now a year down the road, when you should have taken Patrickt and my advice, you know we would never tell you "We told you so" or would we??? I think you can guess the answer Cheers Buddy.

Well, Tom ....I'll be the first to admit further down the "track" if I'm wrong. So, at this point in time, I'm going the "standard" route

Cheers!

Glen,

Counter to the valued input of our fellow Cobra owners in favor of a lightened flywheel, I am with you.

The Tom Lucas (FE Specialties) built 302 in my FIA has a standard weight flywheel. The car is quite responsive, easy to drive and has smooth take offs from a dead stop. Granted, the motor does not have the quick rev, rise and fall of a race motor when you blip the throttle, it's a street car, not a race car and I am OK with that.

It all depends on what you intend to do with the car and what your expectations are. You may change your mind once you have driven your Cobra for a while and if so, the flywheel and associated bits can be changed.

Time will tell and the great news is, you are getting very close to finding out, hopefully very soon. When that happens, we will all be cheering for your Glen, this has been a very long journey and the next chapter is just around the corner.

Thanks Tim, my "learned/experienced" friend! At this point in time, I'm OK with that too

Cheers,

[xb-60]

Tom and Patrick - it's OK, I still love you

Cheers!
Glen

[Alfa02]

Ditto Glen.

[patrickt]

And Tim is right on being able to change stuff. If you don't like whatever you choose for a clutch/flywheel combo then just change it. Heck, I'm going on almost twenty years with my ERA and I'm still changing stuff.

[xb-60]

Yeah, yeah... I know I can change it.... but changing it means engine and gearbox out again, so ideally I want to get it right first time
